This post is part of a series counting up to Earth Day on April 22. Check back for the rest of the 22 tips!

Spread green habits for Earth Day. The idea is that when you do something nice for someone, they’ll hopefully adopt a new habit like taking their own bags or recycling. Here are some some ideas for you.

Buy a few reusable bags at the register at your favorite store and ask the cashier to give them to the person in line behind you. If you’re shy, just do this when no one is waiting behind you, and they’ll have no idea who to thank. Still too shy? Then, organize a sewing party to make reusable bags to donate at shelters or food banks.

Another idea: Give away a recycling bin! Ask your non-recycling neighbor or friend if he or she would like to try out recycling. If you get a “yes,” explain how to sort the recycling for your city, and even offer to take it to the recycling center if needed.

Finally, when you’re doing your spring cleaning, don’t forget about the puppies and kitties! Instead of throwing away old blankets or towels, donate them to your local animal shelter or animal hospital. They’re very helpful in that environment, plus you’re allowing the shelters save funds.
